introduce a BufferedStackTrace class, which owns this array.
Summary:
This change splits __sanitizer::StackTrace class into a lightweight
__sanitizer::StackTrace, which doesn't own array of PCs, and BufferedStackTrace,
which owns it. This would allow us to simplify the interface of StackDepot,
and eventually merge __sanitizer::StackTrace with __tsan::StackTrace.
Test Plan: regression test suite.

ParamTLS (shadow for function arguments) is of limited size. This change
makes all arguments that do not fit unpoisoned, and avoids writing
past the end of a TLS buffer.

Sanitizer source is not affected by _FILE_OFFSET_BITS in general,
but this one file must be built with 32-bit off_t. More details in the code.

__ANDROID__ is a define that comes from the toolchain when building
for Android targets. ANDROID has a different meaning. ANDROID is
defined for _every_ Android build, including those done for host
modules. For host modules, we want to build the regular Linux
sanitizers and builtins, not the one for Android devices. This hasn't
been a problem until now because we only just started building the
sanitizers for the host.

Whitespace update for lint check by myself (Will). Otherwise code and comments by Peter Bergner, as previously seen on llvm-commits.
The following patch gets ASAN somewhat working on powerpc64le-linux.
It currently assumes the LE kernel uses 46-bit addressing, which is
true, but it doesn't solve the case for BE where it may be 44 or
46 bits. That can be fixed with a follow on patch.
There are some test suite fails even with this patch that I haven't had
time to solve yet, but this is better than the state it is in now.
The limited debugging of those test suite fails seems to show that the
address map for 46-bit addressing has changed and so we'll need to
modify the shadow memory location slightly. Again, that can be fixed
with a follow on patch.

We have to #define _WANT_RTENTRY to get struct rtentry, and add headers
that it depends on.
SIOCADDRT and SIOCDELRT also do not exist in FreeBSD 10.1 and were removed
in FreeBSD rev. 263203:
Garbage collect long time obsoleted (or never used) stuff from routing
API.

When compiling with -mfpu=vfpv3, those tests began to pass, like the others
with "Illegal Instruction" error, so removing the XFAIL from them should
get the bot green (and have more tests!).

Clang r219557 introduces libcalls to complex multiply/divide functions.
Since these functions are not available in iOS for arm64 devices, add them to
the static libraries.
